Westwood sits in a pocket of the St. Louis metro where older split-level and ranch-style homes share the neighborhood with newer construction. Missouri summers routinely push heat index values past 105 degrees, and January lows regularly drop below 15 degrees Fahrenheit. Your HVAC system has to earn its keep in both directions. When it doesn't, you need someone who knows how local homes are built, what equipment holds up in this climate, and how to fix the problem the right way the first time. Aire Serv of St. Louis has built a track record for correctly handling these types of issues with HVAC. Westwood, MO pros show up with the right tools, give you a firm price before we touch anything, and back every job with the Neighborly Done Right Promise®. Call for St. Louis HVAC services today!

Westwood HVAC Services for System Repairs, Replacements, and Maintenance
Most HVAC calls in Westwood fall into one of three categories: something stopped working, something is running but not doing the job, or a homeowner wants to stay ahead of a system that's getting old. We handle all three. For heating, that means furnace repair and replacement, heat pump service, heater repair, and radiator work on the older cast-iron systems still found in some Westwood-area homes. Missouri's freeze-thaw cycle is hard on ductwork connections too. Loose joints and gaps let conditioned air bleed into unconditioned spaces, and we check for those every time we're in the house.
On the cooling side, we diagnose and repair central AC systems, ductless mini-split systems, and heat pump setups. A refrigerant leak, a failing capacitor, or a frozen evaporator coil each has a distinct signature; our diagnostic process catches the actual cause rather than treating symptoms.
Indoor air quality is a genuine concern in Westwood, where high summer humidity regularly drives relative humidity readings above 70 percent indoors without a dehumidifier. We install and service whole-home dehumidifiers, humidifiers for dry winter air, UV lamps that mount inside the air handler, and MERV-rated filtration upgrades. Air duct cleaning pulls out the accumulated debris that chokes airflow and recirculates through the home every time the blower runs.
Why Westwood Homeowners Choose Aire Serv
Flat-rate pricing means the number we quote before we start is the number on your invoice. No surprises when the job runs long. Our team services every major residential brand, including Carrier, Lennox, Trane, Goodman, and Rheem, so you don't have to wonder whether we're familiar with your equipment.
Aire Serv of St. Louis carries the Neighborly Done Right Promise®, which means if the work doesn't meet your expectations, we make it right. Westwood's proximity to Ballwin and Manchester lets us respond quickly, and our scheduling flexibility means you're not stuck waiting days for a non-emergency appointment. We also keep our vehicles fully stocked with common replacement parts, including capacitors, contactors, igniters, and pressure switches, so most repairs wrap up in a single visit rather than dragging across multiple days.
